SVP uses the term Syntropy to denote the assimilating, contractive, life-giving force, state or condition. The two terms positive and negative have opposite meanings between Keely and Russell. Therefore to minimize confusion SVP tries not to use either of these terms when indicating a polar condition. Instead we use the unambiguous terms of syntropy and entropy in their place, where possible.

CONVENTIONAL
Uses the terms "negentropy", "neg-entropy" or "Negative Entropy" to denote the contractive, life-giving force, state or condition.Keely Definitions

"We have accounted for the regeneration of the male, positive force which condenses, contracts, generates, integrates bodies which mutually charge each other in the action of contraction." Walter Russell, "The Cyclic Theory as the Cause of Solar Regeneration"Cayce Definitions
"The positive may be considered as the active forces in their activity and the negative as those tending to keep the balance." Cayce (195-70)Nikola Tesla
"A simple way of supplying positive or negativeelectricity to the terminal is to connect the same either to an insulated conductor, supported at some height in the atmosphere, or to a grounded conductor, the former, as is well known, furnishing positive and the latter negativeelectricity." Nikola Tesla in "Nikola Nikola Tesla; Lectures, Patents and Articles", Belgrad 1956
